1. We were originally going to have a patio extended - leaving an original area inplace with an extension of 3 times the existing area. The stone was matched. The contractor suggested lifting the existing, "tidying up the edges" and relaying on existing foundations to gve a more uniform look.
2. A path to the side of the garage was originally flagstoned. It was agreed to remove the flags and replace with matching stone on existing foundations. The area (path) is 1m wide and 8m long.
3. An areato the side of a garden shed - originally flagged but to be replaced with matching stone 2m x 2.5m.
This was all additional work over an above the agreed specification drawing and quotation but there was no discussion on increased costs.
I do not believe that the additinal work is worth £10k - more like £4k
